Breaking the Bank at Caligula's is the final mission in Grand Theft Auto: San Andreas given to protagonist Carl Johnson by San Fierro Triads leader Wu Zi Mu from The Four Dragons Casino, located along The Strip in Las Venturas, San Andreas.
Carl arrives at The Four Dragons Casino, dressed as a Caligula's employee, to meet Woozie and the crew in preperation for the heist. The team get into a Securicar and head towards Caligula's Palace, whilst Carl makes his own way there. On the way, Zero asks Carl if he can hear him on his earpiece, with Carl replying that he can.
Carl enters the casino and uses Millie's swipe card to gain access to the lower floors of the casino. Carl heads into the generator room, where he throws a Tear Gas canister into an air vent, which lands outside the safe and knocks out two security guards.
Zero activates the charges Carl placed at the Sherman Dam, which blacks out the casino. Carl uses night vision goggles and makes his way to the service bay. He uses a Forklift to open the garage door and allow Woozie and the team to enter. The team head towards the safe whilst fighting their way through the security guards. Once at the safe, Zero announces that someone (whilst continually cursing Berkley) is trying to restore the power using the backup generators. Carl heads back to the generator room and blows up the backup generators.
The Triads open the safe using satchel charges and enter to steal the money. Whilst the Triads are in the safe, Carl protects them from incoming Mafioso. Once the team have collected the money, Carl leads the team back to the Securicar whilst fighting the security guards. During the firefight, the power is restored and Zero once again curses Berkley. When the team reach the service bay, they load the money into the Securicar and leave the casino escorted by two members using police bikes.
Carl, acting as the decoy, must make his way to the casino roof. He does so, fighting off more Mafioso, and enters the roof to find the casino surrounded by police. Carl collects a Parachute and jumps off the roof. Once he lands, he escapes from the police and meets the team at the Verdant Meadows airstrip. At the airstrip, Zero admits to Carl that he informed Berkley about the heist, with Carl retaliating by punching Zero in the face. Woozie orders Carl to "calm down" before asking Carl to drive him back to the Four Dragons Casino. Following the mission, an angry Salvatore Leone phones Carl and makes various threats to Carl and his family. Carl taunts Salvatore about the heist and hangs up.
In order to complete the mission the player must:
- Enter the Mafia Casino
- Find and open the swipecard door
- Toss a smoke grenade into the air vent
- Find the swipecard door and open it
- Head down to the service bay
- Use the forklift to open the roller door
- Clear the corridors of security so the team can reach the vault
- Follow the team down to the vault
- Destroy the back up generators
- Head downstairs and check on the team
- Enter the Safe
- Kill the Mafia whilst the team gets the cash
- Lead the team safely back to the van
- Get to the service elevator - remember, you are the decoy
- Get onto the roof
- Follow the rooftops and collect the parachute
- Parachute off and escape in the helicopter
- Escape to the safe house.
If Carl fails the parachute jump to the helicopter, the mission is not a failure; instead, Carl simply needs to jack a vehicle and drive it to Verdant Meadows, while being pursued by the enemy helicopters. If the player has a wanted level of three-stars or fewer, they can escape the police by outrunning them.
- When the Triads jump on the police bikes, their character model is replaced by the standard police biker, resulting in the Triads suddenly turning African-American.
- Carl steals four police bikes in Cop Wheels, but only two bikes are used in the heist.
- It is possible to jump into the vent that Carl throws the tear gas into. If the player does so, they will appear in the Hidden Interiors Universe.
- Despite Carl promising to split his share of the heist with Millie Perkins, there is no evidence he does so.
- No matter what hair style Carl has before the mission, his hairstyle will be the default one from the start of the game. After the mission is completed, Carl's hairstyle and clothing reverts to what it was before the mission started. The clothing isn't returned if it was changed during the mission, it will remain as in the mission.
- The mission is noticeably similar to the film Ocean's Eleven, as by looking into the characters and their plot, one can suggest the it might be an inspiration of the mission itself.
- This mission has the longest name of any in the game, with a total of 27 characters and the second longest in the 3D Universe (The Portland Chainsaw Masquerade in Grand Theft Auto: Liberty City Stories is the longest, with 29 characters). The mission has the third longest name in the series behind Grand Theft Auto IV's I Need Your Clothes, Your Boots, and Your Motorcycle, which has 43 characters.
- The explosives used to blow up the safe door do not harm the player.
- This mission is not required to complete the storyline, and can be completed after the final mission.
